Patent EP-0396424-A1 (EP)
Inventor: DYER DAVID CHARLES
IPC: A47B43/00
Filed: 1990-05-04
Abstract: A foldable structure which can be used as the basis for a wide variety of articles, such as furniture, office equipment, freight containers and portable buildings, is foldable between a generally flat form and an erected, three-dimensional form. A first pair of opposed frame units (10,11) are connected by at least one further frame unit (12), which is hingedly attached to one (11) of the pair of frame units and is hingedly and slidably attached to the other (10) of the pair of frame units, for example by means of swivel cleats (13). Further components are connected to one or both of the pair of frame units (10,11) so that such further components can be disposed in a folded-flat position adjacent to said pair of frame units (10,11) when the latter are in their collapsed state and can be disposed in a second, ready-for-use position in planes at an angle to the planes containing the frame units to which they are attached.

Abstract: The heat load on a greenhouse (20) containing growing plants (27) is reduced by reducing the transpiration of the plants by reducing the rate of convective heat flow of air across the canopy of the plants. This is achieved by heating and dehumidifying the air in the greenhouse during periods of low light levels, such as at night, so that the need for ventilation is minimized.

Abstract: A method and apparatus for the protection of downhole equipment from excessive pressure conditions which includes providing structures of volume compensating material which are designed to resist normal pressures expected in the well bore. One form of the invention has a plurality of half sections (26) of volume compensating material positioned around one of the tubular members (22) in the annulus (20) which has fluids that can increase in pressure to a point approaching damage to the inerior or exterior member of the annulus. In another application a resilient seal includes a recess into which a ring of volume compensating material is placed to allow a place for fluids to flow when they are subjected to overpressure conditions.

Abstract: The printing machine of the invention provides virtually instantaneous drying of the print without the use of an oven, making it possible to print on any type of support and particularly on a support of very low absorption, without such support undergoing any variation or deformation attributable to the heat of an oven. This object is achieved by means of:   - first means for maintaining the application temperature of the inks (14A, 14B, 14C, 14D) within a first fixed temperature range, so as to keep said inks (14A, 14B, 14C, 14D) in a viscous state, and - second means for maintaining the temperature of the printing form (11) of said machine, on the other hand, within a second fixed temperature range substantially distant from said first temperature range and substantially higher than the latter, so as to make said inks (14A, 14B, 14C, 14D) in said printing form (11) more fluid.   The invention also relates to an additive to conventional inks which is composed of a lacquer and of a filler which are intended for making the drying of the ink easier, and of a solvent serving for wetting the filler in order to knead it. This invention is used particularly for intaglio printing, for example for the printing of bank notes and postage stamps. <IMAGE>

Abstract: A method of treatment of androgen-related diseases such as prostate cancer in susceptible male animals, including humans, comprises administering novel antiandrogens and/or novel sex steroid biosynthesis inhibitors as part of a combination therapy. Sex steroid biosynthesis inhibitors, especially those capable of inhibiting conversion of dehydroepiandrosterone (DHEA) or 4-androstenedione ( DELTA 4-dione) to natural sex steroida (and testosterone into dihydrotestosterone) in peripheral tissues, are used in combination with antiandrogens usually after blockade of testicular hormonal secretions. Antiestrogens can also be part of the combination therapy. Pharmaceutical compositions and two, three, four and five component kits are useful for such combination treatment.

Abstract: Air is purified by adsorption to remove water vapour and carbon dioxide therefrom. An adsorbent vessel 30 contains a bed of adsorbent particles having four discrete regions or layers, 34, 38, 42 and 46, the layer 34 being contiguous to an inlet for air to be purified and the layer 46 being contiguous to an outlet for purified air. The layers 34 and 38 comprise particles of alumina or other adsorbent that adsorbs water vapour. The average size of the particles in the layer 38 is less than that of the particles in the layer 34. The layers 42 and 46 comprise particles of a zeolite molecular sieve that adsorbs carbon dioxide. The average size of the particles in the layer 46 is less than that of the particles in the layer 42. Use of smaller size particles decreases the length of the mass transfer zone with the bed at breakthrough and increases the utilisation of the adsorbent material.

Abstract: This invention relates to novel silicon enhanced aluminas (SEAL) and processes to prepare them. The SEAL compositions have a bulk empirical formula of Al 2-x Si x O₃F x  where x varies from about 0.01 to about 0.5. This SEAL material has a three-dimensional pore structure with the pores having diameters in the range of about 20 to abut 300Å, a crystal structure characteristic of alumina, and where the surface of the SEAL has a higher silicon concentration than the interior of the SEAL. The SEAL is prepared by contacting an alumina with a fluorosilicate salt. This SEAL can be calcined to give a calcined seal with a formula Al 2-x Si x O₃F y  where x is as defined above and y varies from 0.01 to x. The calcined SEAL contains both strong and weak acid sites. These SEAL compositions are useful as hydrocracking catalysts.

IPC: H03F3/68
Filed: 1991-08-28
Abstract: Microphones (38,39) sample the sound output from the speakers (20-23) of sound amplification apparatus. The resulting time domain analog signals undergo a Fast Fourier Transform which yields frequency domain signals representative of the intensities of the frequency bands which compose the sound. The intensities or levels of each band are compared to stored permissible level limits for each frequency band. Attenuators (AF1-AF16) respond to signals indicative of band levels being exceeded by respectively attenuating the frequency bands to which they are tuned so the speaker output does not contain frequencies which exceed permissible limits. The time weighted permissible averages for each frequency are also integrated to provide for production of signals representative of the cumulative sound dosage. When total dosage is trending toward exceeding permissible limits for the time during which the listeners are expected to be listening, the cumulative dose signals operate another attenuator (115) to cause the volume emitted by the speaker to drop to a permissible level.
